Fans of the magazine Popular Science--and those who are interested in science and technology--will enjoy the magazine's app, PopSci Reader. The free application grabs the magazine's RSS feed and offers users the most recent articles with images. Users can even read articles offline because the last feed pull remains cached. There's also a "share" feature, so users can e-mail their favorite articles to friends. For more information or to download the application, visit the iTunes store.
